Hey guys im new to the integra world.. Just picked one up last week.. 1998 Rs... I use to drive a 1994 accord coupe h22a powererd.. New to the b seris world..Well my question is im building this car for boost... Theres a b18 in there now but its junk... My question is im planing on gettin a drag kit or greddy kit.. But my problem is i dont know which block to use.. ive used the search button and all... please dont think of me as some noob becuase i laugh all the time when i see guys with 3 posts posting up hey how much horsepower can i get with this setup... the integra was my cousins and we turbo'd it before but it blew with a greedy kit.. he had no feul management.. just an apexi svafc. never turned corretly... I was wondering which block would be best to use 8psi daily 10-12 track... Ive heard about b20 sleeves are weaker than b18.. i just need some advice sorry for the long post

 

I believe the b20 is a bored out b18, so the b20 won't be able to handle as much boost, all things being equal. I'd also post this in Forced Induction, you may get more answers there.

 

If you are going to boost it anyway go with the B18. B20 blocks do not handle boost as well stock. And the B18 blocks are cheaper, so whether you plan on sleeving or not you save money sticking with the B18.

 

The cylinder sleeves in the B20 are weak and can crack under boost.

 

full race stage 1 and bottom end refresh, 8 psi+ all day long, of course this is on the b18.

 

or you can get a b16 short block....bored to 84mm and then sleeve that bitch...then turbo the motha *****....if you got the money of course
